I want to create a form without submit button, just have it be sent without any user action. Here is the code that I have, any help would be greatly appreciated!

<form action="http://<url>" method="post">
<input type="hidden" name="requestXML" value= "<c:out value="${test}" />" />
<input type="hidden" name="clientURL" value= "http://<url>" />
<input id="next" type="submit" value="Submit" />

</form>

Well, you can let JavaScript submit the form onload. Which, of course, isn't reliable.

What i am really wanting to do is send an http post and adding in the key/value pairs in the post. Is there any other way to do this in html besides in a form.

Do you mean you want a URL with a query string? Like http://example.com?key=value ?

no because of the size restriction of sending the data in the url I need to do a post and send the data in the headers.

HTML can't do that unless the user submits the form.

JavaScript can do it automatically, with the usual exceptions (JavaScript disabled, JavaScript unavailable, security/firewall features blocking form submissions, etc.).

how would I do this in javascipt?

thanks for the help!!, it worked perfectly
